Title: Edge extracting device
Inventor: INADA TOSHIO
IPC: G06T7/60
Filed: 1990-05-02
Abstract: PURPOSE:To eliminate the influence of the shift of position of an input image to an output image by setting a prescribed distance between a dispersing surface and a photodetecting surface in the same value as the outer diameter of a peripheral photodetecting element. CONSTITUTION:A distance D0 between a photodetecting surface 1 and a dispersing surface 2a is set equal to the outer diameter of a peripheral photodetecting element 4. That is, the distance D0 is set equal to the outer diameter of the element 4 when an input image given from the surface 2a is received by a center photodetecting element and a peripheral photodetecting element provided on the surface 1, this photodetecting signal is inputted to an arithmetic means, and the differential signal is outputted as an edge extraction signal. Thus the shift of position, etc., of the input image never affects an output image.

Title: Four-wheel steering controller
Inventor: IKEDA HIROSHI
IPC: B62D7/14
Filed: 1988-05-13
Abstract: PURPOSE:To prevent a feeling of physical disorder at the time of steering from occurring by making control over four-wheel steering so as to be done by a transfer signal out of a subcontroller in the case where a nonstationary operating state of a microcomputer constituting a main controller is detected. CONSTITUTION:A main controller 5 being driven by software control of a microcomputer and a subcontroller 7 being driven by a hardware processor are installed there in a parallel manner. Four-wheel steering control is controlled by the main controller 5 when a controller operates in a stationary operating state and, in contrast with this, when a fact that each sensor and the main controller 5 are in a nonstationary operating state is detected, it is made so as to be controlled by the subcontroller 7 in design. When each of sensors 1, 2 and the main controller 5 are all judged to be in this nonstationary operating state and driving continuation by the four-wheel steering becomes difficult, it is changed over to the subcontroller 7 via a selector circuit 6, so that such steering as getting rid of any feeling of physical disorder in a driver is thus performed.

IPC: G05F1/10
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To accurately set a reference value for detecting excess current in a current-detecting apparatus which judges the excess current based on a detection output of a current sensor. SOLUTION: Current sensors 81a-81c detect a current flowing in current feed lines (bus bars) 31a-31c through magnetic field detection elements arranged in the vicinity of the feed lines 31a-31c. The detected current information is branched by a branching circuit. One is taken into an electronic control device 40 as a feedback signal via output buffers 83a-83c, and the other is sent into an excess current-detecting part 82 to detect an excess current. The excess current-detecting part 82 compares the sent current information with a reference value for excess current judgement OVCref thereby to judge whether or not it is an excess current.  Since a power feed circuit for feeding a driving current to the magnetic field detection elements of the current sensors 81a-81c as well as the branching circuit and the excess current-detecting part 82 are formed on a common substrate, this secures the accuracy of the reference value OVCref.
